Yamaha CR 220

I did replace the fuse and it blew right away.I tested the transistors in circuit since I was looking for a "short". I don't have a Dim Bulb tester but looks like a good idea.
 
Check the driver transistors in the amplifier circuit TR115 -118.
In the power supply Check your power rectifiers, diodes, capacitors and regulator components for shorted condition.
A photo of the power supply components may be helpful.

I'm having a hard time finding the service manual as well. Although it looks like ebay has a copy.

Sorry, I was not aware of this rule in the user agreement. I have hereby removed the service manual.

You can get the same, usually piss poor, downloads in the AK database. And that is kosher? WTF is the difference. :dunno: I didn't make the rules. Just pointing out the obvious.

Purge AK database? Probably not. Just thinking outside the box here. :smoke::beerchug: 75-80% or more is from Elektrotanya or HFE.

No argument about the absurdity of HFE's rules, but I still think it's best if people know them :beerchug:.
